摘要	We consider the multiple existence of positive solutions of the following nonlinear Schrodinger equation: -Deltau + (lambdaa(x) + b(x))u = u(p), u > 0 in R-N, (P-lambda) where p is an element of (1, N+2/N-2) if N greater than or equal to 3 and p is an element of (1, infinity) if N = 1, 2, and a (x), b(x) are continuous functions. We assume that a(x) is nonnegative and has a potential well Omega := int a(-1) (0) consisting of k components Omega(1),..., Omega(k) and the first eigenvalues of -Delta + b(x) on Omega(j) under Dirichlet boundary condition are positive for all j = 1, 2,..., k. Under these conditions we show that (P-lambda) has at least 2(k) - 1 positive solutions for large lambda. More precisely we show that for any given non-empty subset J subset of {1, 2,... k}, (P-lambda) has a positive solutions u(lambda)(x) for large lambda. In addition for any sequence lambda(n) --> infinity we can extract a subsequence lambda(ni) along which ulambda(ni) converges strongly in H-1 (R-N). Moreover the limit function u(x) = lim(i-->infinity) ulambda(ni) satisfies (i) For j is an element of J the restriction u\Omega(j) of u(x) to Omega(j) is a least energy solution of -Deltav + b(x)v = v(p) in Omega(j) an v = 0 on partial derivativeOmega(j). (ii) u(x) = 0 for x is an element of R-N \ (boolean ORjis an element ofJ Omega(j)).
